Athlon ranks Auburn's Iron Bowl tune-up Idaho 125th

Athlon Sports doesn't think much of Auburn's tune-up game before the Iron Bowl.

Out of 128 FBS teams, Idaho is ranked 125th in its 2015 preseason rankings. Auburn plays the Vandals Nov. 21 at Jordan-Hare Stadium before closing out the regular season against Alabama at home.

The Crimson Tide are taking it light as well as they're playing an FCS school in Charleston Southern. The Buccaneers closed out an 8-4 season last year with 55-9 loss at Georgia, but barely lost at Vanderbilt, 21-20, and won 47-41 at FBS school Charlotte in overtime.

Charlotte is ranked last in Athlon's 2015 preseason rankings.

Idaho finished 1-10 last season and went 1-11 in 2012 and 2013. The Vandals did have their NCAA postseason ban due to poor APR results lifted because of their academic progress since Paul Petrino became coach in December 2012 and will be bowl eligible for the 2015 season.

Auburn's fourth opponent -- San Jose State -- is 110th in Athlon's rankings. The Tigers beat the Spartans, 59-13, last season at home. They play them Oct. 3 after back-to-back SEC games against LSU in Baton Rouge and Mississippi State at home.

San Jose State lost its last six games last season to end the 2014 season with a 3-9 record.

Athlon does rank seven of Auburn's 11 FBS opponents in Athlon's Top 25 as the Crimson Tide are second behind defending national champion Ohio State. Georgia (10th), Mississippi (11th), LSU (15th), Arkansas (16th), Texas A&M (20th) and Mississippi State (21st). Athlon has every SEC West team in its Top 25.

Auburn's other SEC opponent - Kentucky - is 55th. The Tigers play the Wildcats after a bye week Oct. 15 in Lexington.

Jacksonville State is Auburn's fourth non-conference opponent. The Gamecocks won 10 games and reached the FCS playoffs.

Auburn is fourth in Athlon's Top 25 poll. The Tigers open this season against Louisville, which Athlon ranks 38th, Sept. 5 in Atlanta. The Cardinals went 9-4 last season.
